If the object is nested, shouldn't it just be available as a child of its containing rule? Or is there some css analogue that behaves similarly that might help me understand why this isn't possible? I uderstand thet <LoadDialog> is a rule, but not quite what that implies. I suppose that it would apply to any object named LoadDialog on the python side...
